It might be hard for some to believe, given recent frustration with the nastiness of the politics there, that Congress is “more religious” than the country as a whole.

The Pew Forum on Religion & Public Life reported that one in five U.S. adults do not identify with a particular religion. They classify themselves as atheist, agnostic or “nothing in particular.” But only one member of Congress — and the first member of Congress to do so — publicly identified herself as “none” when asked her religion. Kyrsten Sinema, D-Ariz., is religiously unaffiliated, according too CQ Roll Call.

There are 10 other members of Congress among the 533 sworn in Jan. 3 who do not specify a religious affiliation. That’s under 2 percent — while about 20 percent of the general population don’t. There were only six unaffiliated in the previous Congress.

Of course, secularists, atheists and humanists, would point out that it’s not surprising at all to them that the relative piety of Congress goes hand in hand with sour relations, uncompromising attitudes and vicious smears.

Others faith firsts in the 113th include the first Buddhist to serve in the Senate, Rep. Mazie Hirono, D-Hawaii, and the first Hindu in either chamber, Hawaii Democrat Tulsi Gabbard. And Muslims (with two members) are now represented more proportionately compared with general population in Congress than previously.

Fifty years ago, almost three-quarters of Congress was Protestant. Protestants lost eight seats in Congress in the last election, but still take 56 percent of the seats.

Catholics gained most — picking up seven seats for a total of 163, Pew reports. They now make up 30 percent of Congress, while accounting for 22 percent of U.S. adults.

Jewish members now hold 33 seats — six seats fewer than they did in the 112th Congress — yet they still make up 6 percent of Congress and only 2 percent of the general adult population. Mormons continue to hold 15 seats, or 3 percent, the same as before. They make up 2 percent of the general adult population.

A denomination greatly underrepresented in Congress is Pentecostal. It includes a much higher number of U.S. Protestants — 20 times that suggested by the one Pentecostal member of Congress. While Episcopalians are only 2 percent of the adult population, they hold more than 7 percent of seats in Congress.
